Dr. Paul Auerbach, a professor of emergency medicine at Stanford University, and Dr. York Miller, a professor of medicine at the University of Colorado, were recent medical school grads when they decided to take a backpacking trip high into the San Juan Mountains. Above 11,000 feet, they experienced abdominal discomfort, bloating and premonitory belching. Wilderness medicine had no term for these combined symptoms. They dubbed it high-altitude flatus expulsion (HAFE), and their findings were published in The Western Journal of Medicine, evoking a surprising response. This film is for anyone who has ever gone camping and eaten too many beans.
